Please note, this project, repository and webpage are still under development.
Welcome to the webpage for the Open Redcedar Adaptation Network! Here you will find information, resources, data, and examples of analyses for you to explore.
Together we can study the climate adaptation potential of a important tree to the Pacific Northwest.
Want to help develop or co-produce the Open Redcedar Adaptation Network? Anyone is welcome. Connect with us and let us know you’re interested.

The purpose of this network is to provide opportunities for education about climate adaptation. Anyone is welcome to visit a planting site, measure trees to collect data, do some analyses, and share what they’re learning!
Western redcedar is a important tree species in the Pacific Northwest, but it may need our help to stay healthy. Unfortunately, many redcedar trees have been observed dying recently and we’re concerned about its survival in future climates. You can help accelerate research about the dieback by contributing to the Western Redcedar Dieback Map project. These observations are valuable for understanding why redcedar is unhealthy, but the next step is to explore what we can do about it.
What can we do to help keep this species healthy?
Together we can explore the genetic diversity of western redcedar as a tool for keeping trees healthy. Here we are exploring genetic diversity in a climate adaptation study. Together we can investigate if trees adapted to climates in Oregon will be better suited for upcoming climates in Washington.
We’ve established a network of plantings with trees grown from populations in two seed zones.
There are three plantings of western redcedar trees at three sites in western Washington.
Each planting location has or will have trees from both seed zones planted in rows.

The data of this project are maintained openly so others can participate and learn from the study. If you collect data, please consider sharing it here so others can benefit. More instructions coming soon!
Below you can explore some of the data available already.
Note the trees were not stored in a manner to compare tree heights or diameters at this time. For example, we kept the trees separate to avoid accidentally mixing an Oregon tree with a Washington tree.
We will want to monitor the change in heights and diameters each year to compare between seed zones, sites, and annual clmate variables.
This webpage and data are hosted in a github repository. The content on this page is compiled using R Markdown, but the data is maintained as a .csv file.
